Abstract Sound velocity measurement is a classic experiment in university physics experiments, andcommonly used methords include resonance interferometry method, phase comparison method, and timedilferenee method, On this basis, extends the phase intuitive comparison methord and sigmal superpositionmethod to help students better understand the principle of sound velocity measurement,At the same time, alsoexplores the impact of saltwater temperature and concentration on sound velocity based on AI technology, whichcontributes to the study of sound velocity in seawater and provides ideas for empowering physics experimentalteaching with Al.
